Application filed April 3, 1919.

To all to from it may concewt:

Be it known that l, OLE P. Osmn, a citizen of the Unit-ed States, residing at Baymond, in the county of Kandiyohi and State of lvl innesota have invented certain new and useful Improvements in Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved heater; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings Figure l is a perspective view of the invention placed in a building; and

Fig. 2 is a View in vertical section taken on the line 2-2 of Fig. 1.

The numeral 3 indicates the combustion chamber of a heater supported on the floor of a building a, and provided with a grate 5, fuel door 6 and combined draft and ash door I. A smoke pipe or conduit 8 leads from the combustion chamber 3 and opens directly into a drum 9 which, as shown, is supported on the floor of the building 4 and held in an upright position by wall brackets 10. It will be noted that the conduit 8 and the fuel containing part of the heater are made tight above the grate 5.

Leading from the drum 9 at the bottom thereof, is a horizontal smoke pipe or flue 11 which extends through the outside wall of the building a and opens into the atmos phere. To retain the heat in the flue 8, said flue is covered by placing therearound a casing 12 that is spaced apart therefrom, to afford an air space 13 therebetween.

Smoke and products of combustion rising in the flue 8, enter the drum 9 from which the heat is radiated into the room of the building. The pressure produced by the rising heat in the fine 8 will force the prod- Speeification of Letters Patent.

nets of combustion and smoke down through the drum, and by the time the smoke passes through the fine 11 to the atmosphere, substantially all of the heat in the drum will have'been radiated into the room.

While only a single drum is illustrated, it is, of course, understood, that a plurality may be used. It is further understood, that the radiator may be arranged in various different ways to secure the best results, and the heater, while shown in the same room with the drum, may be located in the base ment or a different room.

The purpose of causing the smoke and products of combustion to pass through the drum is, of course, to remove all of the heat from the smoke before the smoke passes to the atmosphere. I have installed a heating apparatus substantially the same as that shown in the drawings and the same has proven satisfactory.

In place of the hot air drum illustrated, it might in some instance be desirable to construct a radiator having water as a heat conveying medium.

VFhat I claim is A heating device comprising a combustion chamber having a grate therein, said chamber being tightly closed above said grate, a smoke conduit leading from the top of the combustion chamber and extending a considerable distance thereabove, a casing surrounding said smoke conduit and forming an air insulating chamber for the same, a

vertically disposed radiating drum adjacent
